Hypnotherapy

What is it?

Description

Hypnotherapy is a psychotherapeutic intervention using hypnosis, self-hypnosis or hypnosis therapy. Patients attempt to enter into a trance-like state in order to cope better with complaints such as anxiety and stress by actively diverting their attention towards relaxing thoughts.(1) When using hypnosis, subjects are guided by the hypnotist to respond to suggestions.(2) Hypnosis often takes the form of relaxation and imagery, incorporating suggestions which will increase comfort or transform physical sensations such as pain, cold or numbness.(3) The hypnotized person is often relaxed, but at the same time mentally alert.

Application and dosage

Classic hypnotherapy attempts to induce a state of reduced concentration to make the patient more receptive to suggestion. Occasionally, techniques for muscle relaxation are used to reinforce the effect of the hypnotherapy.(4) In addition, passive guided imagery may also be used to assist the hypnotized patient in envisioning pleasant auditory, visual and/ or kinaesthetic situations. (1, 5)

Normally, there are three main stages of the depth of trance: light, medium and deep trance. Light trance is all that is needed for medical purposes. Nearly 90% of the population has the ability to enter such a trance-like state.(6)

As a fundamental rule, people can only successfully be hypnotized if they wish to and cooperate. A willingness to cooperate and a desire to cope with complaints more effectively are prerequisites for efficacious hypnotherapy.(7)

History/providers

The term ‘hypnosis’ is derived from the Greek word ‘hypnos’, meaning ‘sleep’. The history of hypnotherapy indicates that spiritual leaders, priests, healers and philosophers were the practitioners of early forms of hypnosis.

Scottish surgeon James Braid (1795-1860) noticed that many of his patients experienced a trance-like state when they focused on one single spot for a longer period of time. He introduced the words ‘hypnosis’ and ‘hypnotism’ to the medical community. Austrian physician Franz Anton Mesmer (1734-1815) is regarded by some as the father of hypnotherapy. American psychiatrist Milton H. Erickson (1901-1980) is considered to be the founder of clinical hypnotherapy.

Claims of efficacy / alleged indications

There is a wide variety of potential applications for hypnotherapy in a medical context, including pain management, psychosomatic conditions (e.g. irritable bowel syndrome, blood pressure), prenatal courses, physical rehabilitation (e.g. strokes), and use during medical examinations or treatments.(8)

Hypnotherapy has been used in cancer care, together with other relaxation therapies, to ameliorate adverse effects resulting from cancer treatment or to help patients adjust to their disease. In some cases hypnosis is also used to complement pain treatment.(9)

Hypnosis attempts to change the negative state of mind cancer patients might experience and to give them a realistic but positive outlook. By thus providing them with a tool to feel control over their emotional symptoms, patients will be better equipped to cope with the psychological and physical consequences of the disease process.

Mechanisms of action

Current theories about hypnotherapy’s mechanisms of action are based upon newer concepts about learning and memory as well as on research about how stimuli are perceived and processed.

Hypnotherapy is intended to activate specific patterns which are critical to processes of learning and memory; it takes place in a way that facilitates people’s ability to modify their experiences and behaviours. Hypnotherapy circumvents the process of consciously addressing certain topics and content while concurrently stimulating implicit learning processes and making it easier to ignore disruptive stimuli.(10)

Prevalence of use

A systematic review of prevalence data about cancer patients’ use of complementary and alternative medicine estimates that around the world, between 0.5 and 11% of cancer patients use hypnotherapy.(11)

Legal issues

Both the British and American Medical Associations officially recognize hypnosis as a legitimate medical procedure. As an efficacious treatment modality, hypnotherapy belongs exclusively in the hands of qualified therapists.

Hypnotherapy has not yet been regulated in the UK. Most hypnotherapists are licensed medical doctors, registered nurses, social workers or family counsellors who have received additional training in hypnotherapy. The practice of hypnotherapy, however, entails virtually no standards or requirements for minimum training, practical experience, or demonstrated competence.

Costs and expenditures

The cost of a single hypnotherapy session will vary between countries and states, ranging from ~€30 to ~€400.
